First thing I'd try is either reinstalling the video drivers already installed or installing the latest for the card/chip you have.
Old PC with two wide-screen monitors, separate NVidia graphics card, resolution set for 1366 x 768. Still running XP (Yes - I know!). Sometimes during the slow-ish boot up (desktop nearly complete) screens go blank with an "out of range" error, recommending 1366 x 768, which the system is already set for, of course! Sometimes resolves itself by going to "last good configuration" in safe mode but a little annoying.
